Welcome to the Michigan FBody Association website.
The Michigan FBody Association is a centralized website for FBody enthusiasts to discuss what's going on in the Michigan area. MiFbody.com was created to allow for an easy one-stop place to find out what's going on in Michigan as far as FBody events, to find out what clubs are available in your immediate area, and for an easy place to post classifieds for items you want to sell! Our goal was to create a more close-knit community of FBody enthusiasts in the state of Michigan, and to bring Camaro and Firebird enthusiasts alike together for some amazing FBody events!
The most important thing to know about the Michigan FBody Association is that we are NOT a club! The Michigan FBody Association is open to everyone, and is a community. Thus, we will have get togethers, casual cruises, events, and such like that, but this is not an exclusive club and it's 100% free to join this site! So what are you waiting for? Register now!
If you have any problems with the registration process or your account login, please contact us!

I can't find any markings to tell me what kind of unit I have.. I was told it was an auburn unit by the seller.. How do I verify what kind it is? There are numbers on the ring gear, I know it is 3:70 ratio.. Also posting pics of the locking tabs, do I need to worry about the one that looks twisted?
Edit: looked at some images online, thinking it is a tru trac....
The tab is fine. They can be placed as necessary to lock the retainer at the appropriate spot for proper backlash. Need a better pic of the posi but it looks like it could be a variant of the Ford Trac-lok which is what I run.

That was my initial thought, trac-lok. So hard to tell looking at pics.. I will look at it more closely today and see if I can get some better pics.. Be nice if they put some visible marking on them. I sure can't find any..

The Trac loc has been around for a long time and has had some minor variances. I'll post a pic of mine tonight when I get home. If it's a trac-loc it will have a ford part number cast onto it.
You probably won't be able to see any numbers unless you remove it from the carrier
Ahh, I thought based on James post I would be able to see a number as it is.. I don't want to take it apart, but I need to figure out what I have.. If it has clutches I will need posi additive correct? Sorry I am still learning, but confident I could rebuild a 9" any day of the week now.. lol
